Your calendar is no doubt stuffed with holiday cocktail parties galore right now, so we figured you might welcome a few festive beauty ideas for all of these upcoming events. (Plus, New Year's Eve is right around the corner!) Rather than reaching for your favorite red nail polish or attempting some sort of updo, this season we highly suggest adding some glimmer to your signature celebratory look via metallic beauty products. Whether it's stunning silver eye shadow inspired by Nicole Richie or a stone-studded barrette like Eva Mendes, these molten metals are a must-try trend for the holidays!
